content="人为活动产生的多种污染物排放深刻影响大气环境，环境因子的变化又对人为排放过程形成约束。“科学之光——人为活动与大气环境”课程由环境学院赵瑜教授主讲，旨在引导来自不同专业背景的同学们思考和发现生活在其中的大气环境相关的科学问题，通过课程讲解与观测实践的结合，提升学生对环境大气科学的兴趣和认识，完成基本科研技能的培养和意识的训练。 1.理论学习——认识大气环境与排放课程初始，赵瑜教授鼓励每一位同学自我介绍，并询问大家对课程的预期和希望获得的知识与技能，鼓励同学们在课上勇于表达、积极交流。授课阶段，赵瑜教授首先从仙林校区的大气能见度切入，介绍了自己亲身经历的PM2.5污染的变化，激发同学们的兴趣。随后，赵瑜老师详细讲解了大气污染的来源、变化、归驱与危害，为同学们构建起对大气污染问题的初步认识。课程深入讲解了大气污染的排放来源、不同PM2.5组分的形成方式和污染的源排放治理过程与成效。最后，课程总结了大气污染防治行动计划实施以来我国的大气污染治理成效，并通过与国际标准的对比提出了未来展望。
